Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious construction makes it self-aligning and therefore not susceptible to axial or bearing housing angle errors or shaft bending. It is suitable for installation errors or shaft deflections that cause angular errors. In addition to being able to withstand radial loads, the bearing can withstand axial loads in both directions.
Spherical roller bearings have a cylindrical shape and a conical shape. The conical tapered bore has a taper of 1:30 and 1:12. The conical inner bore bearing is equipped with an adapter sleeve or a withdrawal sleeve. The tapered bore self-aligning ball bearing can be easily and quickly assembled on the optical axis or step machine shaft.
Spherical roller bearings are available in: spherical roller bearings (20000CC type); tapered bore spherical roller bearings (20000CCK type); spherical roller bearings (20000CC/W33); tapered bore spherical roller bearings (20000CCK/W33 type); Spherical roller bearings (20000CCK+H type) mounted on the adapter sleeve; 6 kinds of spherical roller bearings (20000CCK/W33+H type) mounted on the adapter sleeve.
